WALL-BUILDING FORM.

Application filed August 13, 1927. Serial No. 212,759.

This invention relates to forms for building concrete walls, and the general object of the. invention is to provide forms which may be.

readily set up and as readily taken down and by which the walls of a building may be cast of concrete with an air space left in the middle of the wall and extending vertically upward and communicating adjacent the founelation, thatis in the second course above the foundation or at any other desired point or course, with the outside air by transverse tubular ties so that the air may pass into the air space at the lower portion thereof and rise upward through the air space and be disQ charged at the upper end of the wall, the two separated portions of the wall above the tubular ties above referred to being connected by ties which are closed at their open ends by concrete when the wall is finished.

A further object of the invention'is to provide forms of this eharacteiwhich may be used to form walls of different lengths, which may be readily shifted, which may be readily 7 put togetherto form the corner of a building, and which may be used inconnection with certain false or temporary work to leave proper spaces for door and window frames.

A. still further object is to provide oppositely disposed wall forms with detachable cores used for the purpose of forming'recesses for the ends of the floor joists.

Another object is to provide means whereby the mold sections 1nt-o which the concrete is ran' med may be held in proper spaced relation and against any tendency to spread. 7

Other obgects have to do with the particular details of constructionof these forms and.

mold sections and the particulararrangement of the parts as will hereinafter more fully appear.

' My invention is illustrated in the accompanaying drawings, wherein I Figure 1 is a top plan view of a wall mold constructed in alrcordance with my invention;

In Figure 1', I have illustrated the mold sections of my invention as used to form two sides of a building and a corner thereof. It will be understood, however, that the sections may be used to form a straight wall just as well in a manner which will be later stated. As illustrated, my improved building form comprises outer and inner mold sections 10 and 11, these being practically alike, but the sectionlO being shorter than the section 11. enjoined with these sections 10 and 11 are the sections 10"" and 11 The sections 11 and 11 are longer than the sections 10 and 10 so that the sections may be used to form the corner of a building, but these sectionsmay be also placed with thesections 10 and 11 on the exterior of the wall and the sections 1O and 11 on the interior of the wall where a straight I section of Wallis being formed (see Figure 2).

Coacting with the sections 10 and 11 or 10 and 11 are theinner core sections 12 and 13 and 12 and 13". These core sections 12 and 13 have a length somewhat greater than the sections lOand 10 but shorter than the sections 11 and 11 so that they may turn the corner where the corner is being molded.

' These sections 12 and 13'or 12 and 13*.are

bars F16. ,Each of lfOIlIlQCl'Wl'tll outstanding lugs tor the purused, these irons being formed with bayonet joint slots 21 throughwhich these screws may pass. By loosening the screws, it is obvious that thoangle iron may be taken oil to permit the-sections to be released from their engagement with each other. V Yhore' the sections are disposed one in advance oi the other in a straight line, as in forming a straight section of wall, the flat plates 2O are utilized having tl1e-bayonetslots 21 through which the screws 19 engage. Vv hile these angle plates are used upon the outside corner of the builder, no such angle j i latcs"nced be used upon the insidecorner. 'll us it anything 1s a little out of square,- thoinside corner can give a little.

For the purpose of holding the sections 10 and 11 in spaced relation against the pressure of theconcrete when it is rannned home, I

provide the transverse locking baa-s23 shown in Figure 3, each of these locking bars belng adapted to be lllSOl'bGCi 111 the corresponding slot 17-and each of these locking bars being slottechas at, 24, so-asto interlock with the ,these locking i bars 1s pose of supportin the wedges 26 which GX- tend downward through the channels 14, th esc channels 1% con'frontin each other when the core sections l2and 13 are placed in confronting relatioinas shown in'l igure'. These wedges will hold the, core sections spaced apart the desired distance to form a central air space in the wall. The sections 10 and 11 and 1O andll'arc formed with transverse apertures 27 for the passage of bolts 28.

lhcse bolts 28 may carry the nuts29, one of those nu is ha ring a handle 30 'whereb y it may be readily unscrewed. 'lhc bolts 28 pass tl'ircugh tubular tie rods or tie'bais These tie rods in the second course above the foundation are. ten inches long so as to en tend entirely through the wall and are perforated-at the center, as atill, (see l igurd so that'atter the wall is formed air may enter through the ends-otthe tubes 31 and pass upward into the s ace between the inner and Above the second course these tie'rods are only nine inches long. 'All of the tie bars are ji'eterably flared at C1161? ends so that the tie tween the mold sections.

' upon the previoul,

taken out, the angle irons 20 reniovec, han'dled nu bars interlock with the concrete placed be These tie bars are made of ordinary pipe and may be made of scrap pipe and the flaring is very readily accomplishedin an'obvious manner. Thus the tie bars are very cheaply made and of the nest ordinary inaterials.

lt will be seen that these tie bolts and the tie rods disposed adjacent the lower inar- ;gins oi the mold sections, while the locking bars engage the upper one s of the vertical members 16 and hold the mold sections from spreadin Used in connection with the mold sections are the bulkheads 33 which are engaged with the ends of the mold sections 10 and 11 and 1G and'll by means of the angle irons 20 previously described. Also used in connection with the mold sections adapted to be applied upon the inner faces of the sections ll) and 11 or 1O and 11 are thejoist pocket core plat :4. 'lhese,-as shown in Figure 12, consist of an outer plate ill and an inner 'Jlate 3d, the inner. plate being narrower than the outer olate so that the outer plate will: project above and belowfthe inner plate and this inner plate being formed With. the inwardly projectingjoist pocket cores 35. Except as hereafter stated, these pocket cores are disposed at a distance of si"teen inches on centers, each core having a straight side and an inclined side. The

last core 35, however, is detachable but ,1

. 2151011 in place is disposed at a less distance than, sixteen inches from the next adjacent This core 35 is formed with a lug 35" which is adapted to be inserted between the outer and inner sheets 34: and 3 h.

There are two of these core-supporting plates, one equal to the length or. the section 11 and theother equal to the length of the section '10, and the short one alone has the re movable core torni The two plates from which the core support is formed are of galvanized iron and the two plates together have a thickness of about /8". Qhe two sheets are attached together in any suitable manner and when stood on edge are two inches higher than tie outside sections of the builder, tha is the sections lOand 11 or 10 and 11.. Thus when in place the sheets project abovethe builder two inches. Thus, as shown in Figure 5, the joistftorin' will rest iu'in'icdiately termed concrete portion of the wall and the upper end will project above the side oi the form about two inches, as before stated.

in order to explain why this. upward jection is necessz I will have to ex just how. the forms are removed and rc-set. iter the builder has been tainped tightly ll of concrete, then the wedges should be pulled out, the b .llqheads. taken off, the core the s removed ironi' the tie rods or bolts 28, then the sections 11 and 11 are r movedbeiore the tie rods 28 are taken off, then the tie bolts are removed, and then the sections 10 and 10 are removed. The joist taken over to the opposite side of the foundation, that is where the other end of tl'iesesame joists will be, set the builder up at that corner, but betore placing the wedges in position,

remove the oist pocket form, bring it over to where the builder is now set up but do not turn it around with the other end toward the corner but turn it upside down so that what was formerly the bottom edge now becomes the top edge and, of course, cumstances there'will be a portion extending downward over the outside face of the wall, as shown in Figure 5.v lVhere the joist pocket forms are not intended to be used, then a plate of the same thickness is to be used under the angle iron on the bulkhead, this plate being equal in thickness to the two sheets 34 and 34. This plate will be about two inches wide and as long as the builder high and with holes bored so that the screws 19 may pass through these holes. Such a plate must a lways be used when the joist pocket form is not in use, for otherwise there would be no room for the sheets to be placed between" builder and wall. I

As before remarked, the oist pocket form 35 which is removable, is not separated from the next adjacent joist pocket form by as great a distance as the other joist pocket forms. This is necessary because of the way in which lumber and lath are cut when they come from the mill, but where two joist pocket molds 34 are laid end to end, the regular spacing is carried onto the other sheet. Thus the spacing is the same everywliiere, except the one place at the end, and when this device is to be used any where except on a corner, the odd space makes it necessary to remove the end pocket form The joists are spaced regularly from one end of the buildingto the other. j

Coacting with the core sections 12 and 13 when a window or door opening is to be termed are the metallic plates 36 Figure ll) which are inade o't galvanized iron and are adapted to be telescoped over the core sections 12 and 13. Used. in connection with these plates 36 is a tapering core 37 (see Figure 1?; and Figure 14) which is used to form the reress for the sash weights. This core 37 has projecting lugs 38 which can project, as shown in Figure 14, into the space between the plates 36. The core is formed with a hand hold 89 and with upwardly projecting lugs 39 for temporary nailswhereby the core may be held to the jack a and the temporary wood strips Z) shown in Figure 1e.

In the use of the mechanism, the sections 10 and 11 and 10 and 11 are used for forming under these cirthe foundation, except that no tubular tie bars aredisposed through the foundation of concrete and no center core is used, tin tubes being used in place of the members 31. Considering that the foundation is already in, then to set up the builder on a corner, take the sections 10 and 11, put the handled bolts 28 through the holes therefor, through the hollow wall tie and through the holes. in the section 11. The handled nuts are then placed in position upon these screws. The joist recess molding plates 34 are then put in place and the bulkheads 33 put in place. The coresec tions 12 and 13 are then inserteddownward between the sections 10 and 11 and 10' and 11. These core sections will stand up slightly above the lower sections for the first course only,inasmuch as these core sections will rest uponthe foundation.

It will be understood that after the foundation is built, the sections 10 and 11 will be so disposed'over the foundation that the ties 31 will rest upon the foundation, as shown in Figure 5. The angle irons 20 will be used at the corners and for holding the bulkheads in place, as previously stated, or if a straight section wall is to be built, the fiat irons 20 will be used to jointhe sections. The sections are to be leveled up true and if one end is low, the handled nuts are loosened at that end and the builder is-raised up level and the nuts tightened again. After the builder is set up, a little concrete is placed in the outside space between the core section 13 and the wall 11 but this is for the first course only. The

wedges 26 are then put in place in the grooves crete, using a inix such as used r01- making concreteblocks, which mix when. used with a small amount of water will set quickly, the buildercan be taken apart. After a corner is made audit it is desired to build a straight wall, the section 11 will pair with the section 11 and thesection 10 with the sectionlO and the core sections will, of course, pair in an obvious manner so as to provide for a longitw din-ally extending straight core section. Any oi these pairs can be swung around andused with the other end forms when needed to come closer to or further from the door and window frames. The second time around. the

Thus, for instance, it the joist pocket form was used along the wall iintii it cameto 'a place where joists did not go into the wall on account of.

a stair opening, for instance, then in that particular place the joist pocket form would be left out, but when the wall form was placed at the other side 01'? the stair opening the joist pocket form would be put in place and used and it would be impossible forit to be placed wrong and the regular spacing oi? the joist is continued wherever necessary with the oists spaced a standard spacing apart Where the joist pocket formers 3d are not used, then metallic plates of the same ess are to be disposed between the cut "aces of the sections 11 and '11 (or wha c and the angle irons 20 or flat irons 29 so as to com ensate for leaving out the sheet metal lates and 3d and yet make the wall of same thickness throughout.
